Main Circuit Scheme
The GGD's main circuit offers an impressive array of 129 schemes and 298 specifications, ensuring a perfect fit for diverse requirements. AC Low Voltage Distribution CabinetExcluding auxiliary circuit modifications, the GGD1 model provides 49 schemes and 123 specifications, GGD2 offers 53 schemes and 107 specifications, while GGD3 includes 27 schemes and 68 specifications. These schemes have been meticulously crafted by incorporating insights from design experts and user feedback, fulfilling the diverse needs of power plants. With a remarkable rated current of up to 3150A, they are ideal for distribution transformers up to 2000kVA. Additionally, the GGJ1 and GGJ2 transmission compensation cabinets are tailored for reactive power compensation, available in 4 circuit schemes and 12 specifications.
Auxiliary Circuit Scheme
The auxiliary circuit design is strategically divided into power supply and power plant schemes, offering ample space in the BGD cabinet for secondary components. Moreover, NLS has innovated the LM23D current transformer, catering to the specific relay protection needs of power plants and specialized users.
Main Bus-Bar
For optimal cost-effectiveness and performance, a single aluminum bus is recommended for rated currents below 1500A, while a double copper bus is suitable for currents above 1500A. These prototypes have passed rigorous type tests, ensuring high reliability. Additionally, users can request bus replacements to meet specific needs, with all overlapping surfaces meticulously treated with the pond tin process for superior conductivity.
Selection of Electrical Components
The renowned GGD Type AC Low-Voltage Distribution Cabinet primarily utilizes cutting-edge electrical components that are widely produced in China. Balancing economy with practicality, it retains reliable older components like DZ10D and D220, while avoiding obsolete products, ensuring sustained performance and sustainability.
NLS's exclusive HD13BX and HS13BX rotary operated knife switches are tailored for the BGGD cabinet's unique architecture. These components revolutionize operational mechanics while preserving the traditional strengths of existing designs, delivering exceptional practicality and dependability.
When design departments elect to incorporate advanced electrical components with superior performance, the GGD Type AC Low-Voltage Distribution Cabinet rises to the challenge with remarkable installation flexibility. It seamlessly accommodates component updates, ensuring that manufacturing and installation proceed smoothly, without hindrances, thus future-proofing your investment.
Elevate the dynamic stability of the main circuit with Kexun Electric's innovative NLS-designed ZM combined bus clamp and insulation support, crafted specifically for the GGD cabinet. Our bus bar clamp, composed of high-strength, high-flame-retardant Pp0 alloy, offers unparalleled insulation strength and exceptional self-extinguishing capabilities. The unique, versatile structure allows effortless configuration into either single or double bus bar clamps, simply by adjusting its modular design. Additionally, the sleeve-type molded joint insulation support combines low cost with high strength, effectively addressing the shortcomings of previous products by enhancing the creepage distance.
Installation and Use
Upon arrival at the receiving location, it is crucial to inspect the product for any packaging damage. Should any issues arise, promptly notify the relevant departments to ascertain the cause. For products not immediately slated for installation, ensure they are stored in locations that adhere strictly to the specified normal usage conditions, preserving their functionality and integrity.
Product Installation
Product installation must adhere meticulously to the provided installation schematic diagram (refer to the attached figure). Users are responsible for supplying the basic channel steel and bolts. For installations where the main bus is plated in a continuous tin-coated row, ensure the overlapping surfaces are meticulously repaired, leveled, and cleaned. Apply a coat of neutral vaseline or other protective measures, followed by secure fastening with bolts to ensure optimal stability and performance.
